cmiVFX Releases Brand New Houdini Audio Driven Animation Video For FX TD's
High Definition Training Videos for the Visual Effects Industry
Princeton, NJ (April 5th, 2012) cmiVFX has released the latest treat for its SideFX Houdini training product line titled "Houdini Audio Driven Animation". Modern technology gives us many opportunities to add a new sense to the common things. We can listen to the sounds of the universe, we can view the deepest ocean or we can visualize musical composition. In this video we'll do the latter. Using the time tested and industry proven Houdini procedural approach and its unique set of tools in CHOP, SOP and POP contexts, our piano will play in unusual way. In this unique training video, the user will learn techniques on how to extract data from MIDI files and how to use that data for piano animation and particle kinematics. As usual, we through back a nod to the well known cmiVFX style for making videos and break loose on some killer procedural modeling techniques using loops, Hscript and python scripting. For particles we'll use VEX, both for building ballistic trajectories and creating collisions. *When your done watching this video, you will be left with a Houdini digital asset that can be reused again and again in your procedural pipeline.
Short Description - Audio Driven Animation.
In this video, we will be learning how to create "animusic" like animations in Houdini by implementing the highest level of technology available today. ANYONE can download and use Houdini today thanks to the SideFX Apprentice program.
Here at cmiVFX we maintain a current training library for the latest versions of popular software titles. When it comes to high end CG and VFX training, there is only once choice... cmiVFX! Dont forget about the cmiSubscription plan! Get one today. cmiVFX launched the most affordable subscription plan in Visual FX Training History for only $399 USD, and if you were a subscriber, this New Training Release would already be in your account. This video is also available a-la-cart in our brand new HTML5 player system.

Anton will take you through an overview of the whole system, its parameters and all its possibilities.
In this chapter we will cover some simple mathematics, which will help us to create ballistic trajectories for the particles being used. Starting with a parabolic system, we will build equations to govern each particle animation. These very same equations will be implemented in VEX code later in the video.
Constructing A CHOP Network
This chapter is about parsing MIDI files and extracting the data. For our purpose we need three types of information to drive particles and piano keys, so we will build three branches in CHOPs to process MIDI data.
This portion of the video will entail the creating of the piano keys and placing them into a keyboard structure so that they can be used in the following chapters. We will use prebuilt geometry of the keys and a line SOP to copy this geometry using copy SOP with several mathematic expressions to showcase the power of Houdini proceduralism.
Creating Python SOP For Placing Keys
Now that we have completed all the previous steps, we will need to diagnose and fix some issues for the utmost keys of the keyboard to hep prevent holes in the piano. So we should substitute some piano keys with other ones. To make it possible, we will use the PYTHON SOP to change the point attributes of the template geometry our keys are copied to.
Spherical Firing Mechanism
In this chapter, we will create the miniature sphere firing mechanism that ties this whole project together. This mechanism is an analogue of a piano musician, but it fire spheres against fingers. Again, with prebuilt geometry we'll build the machine with some animation based methods.
Anton will construct the main hull portion of the piano keyboard equipment that will give this project a more polished appeal. He will use several geometry pieces to build a procedural piano, where we can change total number of keys. And also he will merge all piano stuff together (hull and a keyboard).
Building Adhoc Geometry For Particle Kinematics
Now we will be building some miscellaneous items which will assist us in the particle animation sequence. There are two types of adhoc geometry in this project: points, where spheres should land and the points from which spheres should emit. We'll construct the points and incorporate them in.
Using VEX For Particle Kinematics
In the part of the video we will be implementing math earlier built in chapter 2 into VEX code for Particle Kinematics. You will see how simple math could do the beautiful work. Just using several lines of code in Houdini, and Voila, our particles will fly using parabola ballistic trajectory!
This chapter will help the user learn to make collisions and bounce animations manually by using VEX as the backbone. Let's speed up our simulation with manual collisions. VEX is an ideal tool to handle bounces from the keys and collisions from the floor and to make particle simulation more predictable. As an option we'll use the Collision POP.
Conclusion And Alterations
This is the final chapter, in which Anton makes several adjustments and variations so the end user can learn more about implementing this kind of technique into their own workflow. He'll tell some info about nodes permissions to lock and unlock operators, and of course, we'll create the final Houdini Digital Asset.
About The Artist
Morzhakov Anton is the 31 years old Russian VFX freelancer and professor of high mathematics. *He studied mathematics and physics in college and graduated from university's math faculty where he also got his Ph.D. in math. With more than 9 years of experience in 3D animation and vfx, apart from teaching, Anton is currently starting to work in R&D. His main passion is to build automated systems that could be governed by a limited set of parameters.
